This is a truly "Intergalactic Counting by Color." A boy simply recounts the alien friends he has made in a singular counting progression. This is a great book for introducing children to counting, as well as fun creatures that will surely enrapture young eyes. Children will have to differentiate between the the aliens in the scene and the other beings present, which is made evident by the color contrast and uniformity of each specie of alien. A nice title to have on the math shelf!
